# How to write an equation in slope intercept form with 2 points

Intercepts and linear equations in machine learning and science The slope intercept form calculator tells you how to find the equation of a line for any two points that this line passes through. It will help you find the coefficients of slope and y-intercept, as well as the x-intercept, using the slope intercept formulas. Read on to learn what is the slope intercept form of a linear equation, how to find the equation of a line and the importance of the slope intercept form equation in real life. What is the slope intercept form? Using the Point-Slope Form of a Line Another way to express the equation of a straight line Point-slope refers to a method for graphing a linear equation on an x-y axis. While you could plot several points by just plugging in values of x, the point-slope form makes the whole process simpler.

Point-slope form is also used to take a graph and find the equation of that particular line. The point slope form gets its name because it uses a single point on the graph and the slope of the line.

Think about it this way: You have a starting point on a map, and you are given a direction to head. You have all the information you need to draw a single line on the map. The standard point slope formula looks like this: In this case it denotes a specific y value which you will plug into the equation.

The variable m is the slope of the line. Example 1 You are given the point 4,3 and a slope of 2. Find the equation for this line in point slope form. Just plug the given values into your point-slope formula above. Your slope was given to you, so where you see m, use 2.

Your final result should look like: Your point is -1,5. Create the equation that describes this line in point-slope form. Try working it out on your own.

Point-slope form is all about having a single point and a direction slope and converting that between an algebraic equation and a graph. In the example above, we took a given point and slope and made an equation.

Example 2 Find the equation in point-slope form for the line shown in this graph: To write the equation, we need two things: It is simple to find a point because we just need ANY point on the line. Note also that it is useful to pick a point on the axis, because one of the values will be zero.

Finding the slope requires a little calculation, but it is also pretty easy. Therefore the slope of this line is 2. You could have used any triangle to figure out the slope and you would still get the same answer. Putting it all together, our point is -1,0 and our slope is 2. We know how to use the point-slope form, so the final answer is: As you can see, point-slope form is nothing too complicated. It is just one method to writing an equation for a line.

Babies usually follow a straight line of increasing body length as they start growing.

This baby was born 20 inches long (y-intercept), . But the best part about the slope-intercept form is that you can read off the slope and the intercept right from the equation. This is great for graphing, and can be quite useful for word problems.

This can be done by calculating the slope between two known points of the line using the slope formula. Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.).
